Abstract: Within the framework of German-Egyptian cooperation, an agreement was signed between KFA Jülich (Research Centre Jülich) and AEA Cairo (Atomic Energy Agency) concerning the implementation of a development and test programme for the incineration of low-level radioactive waste in Egypt. For this purpose, the LAWI ($\underline{L}$ow $\underline{A}$ctive $\underline{W}$aste $\underline{I}$ncinerator) prototype incineration plant was devised and constructed by KFA Jülich according to the principle of the Jülich thermoprocess and installed at the Egyptian research centre Inshass. In parallel, AEA Cairo devised and constructed their own operations building for this plant with all the features, infrastructural installations and rooms required for operating the plant and handling and treating low-level radioactive wastes. The dimensions of this incinerator were selected so as to be sufficient for the disposal of solid, weakly radioactive combustible wastes from the Inshass Research Centre and the envirorenuent (e. g. Cairo hospitals). However, the test and operating programme planned for this prototype plant only provides for the combustion of radioactive waste in a second stage. The first stage contains an extensive test programme for the combustion of conventional waste aimed first of all at training the crew and thoroughly testing the plant and optimizing it, if required. Moreover, this stage will serve to closely examine to what extent this processcan also contribute towards solving country-specific problems in the disposal of conventional combustible wastes such as household and municipal refuse. Theresults obtained and experiences gained can serve as a basis for developing a long-term waste disposal strategy. Incinerators of different size and substantiallysimplified design can be used according to this operating principle, depending on demand. Since LAWI was specifically designed for the combustion of low-level radioactive waste, a sophisticated plant design was required for compliance with the regulations for handling radioactive materials. Conventional plants are less sophisticated and therefore much easier to design and operate. After successful testing in Jülich, the complete plant (approx. 19 t) was transported to the final Inshass site, i. e. by ship from Hamburg to Alexandria and by truck from Jülich to Hamburg and from Alexandria to Inshass. The Egyptian LAWI crew will be responsible for the further operation of LAWI and the implementation of the test and operating programme. This crew was set up at an early stage enabling them already to gather experience during the construction and test phase. The crew was thus familiarized with the function and operation of the plant and trained in handlingradioactive waste during several earlier visits to KFA Jülich. LAWI was set up and installed in the operations building at Ti shass by the Egyptian crew, whereas finalassembly and commissioning were jointly carried out by a German and the Egyptian crew.
